Modal Fails To Close More Than Once Through data-dismiss field

Created by: larryprice

Using the example on http://getbootstrap.com/javascript/#modals (and embedded in my own application with proper css/js files) only allows me to hit the 'X' button or a similar 'Close' button once. Relaunching the modal and hitting the 'X' button again does nothing. Clicking off the modal works. Through testing, adding

onclick="$('#begin-new-period').modal('hide');"

to the close button is a viable workaround. The code in question:

  <!-- Button trigger modal -->
  <a data-toggle="modal" href="#myModal" class="btn btn-primary btn-lg">Launch demo modal</a>

  <!-- Modal -->
  <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
          <h4 class="modal-title">Modal title</h4>
        </div>
        <div class="modal-body">
          ...
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
          <button type="button" class="btn btn-primary">Save changes</button>
        </div>
      </div><!-- /.modal-content -->
    </div><!-- /.modal-dialog -->
  </div><!-- /.modal -->
